This video explains how the direction and gradient of a line on a velocity-time graph can tell us whether an object is accelerating, moving at a constant velocity or decelerating. Velocity time graphs ...

Come to lab (hopefully not late). Most likely listen to a boring (but short) lecture that seems similar to stuff that was also covered in lecture class – but it’s still confusing. Look at some new ...

One of the most basic things students do in a physics lab is to collect data and use that to build a model. Most of these models come in the form of a mathematical function. But here is the problem.

Keywords Learn how to solve particle motion problems. Particle motion problems are usually modeled using functions. Now, when ...
